The entrance to the parking garage during the chase near the end of the film is completely different between shots from inside and outside of the building. In fact, the shots were taken in two separate locations.
The story is supposedly taking place in New York City, but during the automobile chase near the end of the film the principals in their Mercedes drive up Grand Avenue in Los Angeles, passing the Mayflower Hotel and in and out of the Grand Central Garage. In another scene they pop into a hotel lobby with Hotel Stowell, located on South Spring Street, in Los Angeles, in the background. (In fairness, Los Angeles was not a popular vacation destination until the 1950s, so the vast majority of moviegoers at the time would not have noticed this.)
